Abstract
The Lynch syndrome (LS) is an autosomal dominant condition usually characterized by germline pathogenic variants in DNA mismatch repair (MMR) genes. Despite the guidelines now available, determining the pathogenicity of rare variants remains challenging, as the clinical significance of a genetic variant could be uncertain, but it may represent a disease-associated variation in the aforementioned genes. In this case report we will describe the case of a 47 years-old female affected by endometrial cancer (EC) with an extremely rare germline heterozygous variant in the MSH2 gene (c.562G > T p. (Glu188Ter), exon 3) that is likely pathogenic, and a family history consistent with LS.

Abstract
Background Splenectomy is sometimes necessary after abdominal trauma, but splenectomized patients are at risk of sepsis due to impaired immunological functions. To overcome this risk, autotransplantation of the spleen by using a new technique has been proposed, but so far, a demonstration of functionality of the transplanted tissue is lacking. Methods We therefore evaluated 5 patients who underwent a splenic autotransplant in comparison with 5 splenectomized patients without splenic autotransplant and 7 normal subjects. Results We confirmed that the patients not undergoing autotransplantation, when compared to normal subjects, had a higher platelet count, higher percentage of micronucleated reticulocytes (p = 0.002), increased levels of naive B lymphocytes (p = 0.01), a defect of class-switched memory (p = 0.001) and class-unswitched memory B cells (p = 0.002), and increased levels of PD1 on T lymphocytes CD8+ (p = 0.08). In contrast, no significant differences for any of the abovementioned parameters were recorded between patients who underwent spleen autotransplantation and normal subjects. Conclusion These findings suggest that splenic autotransplantation is able to restore an adequate hemocatheretic activity as well as recover the immunological deficit after splenectomy.

Abstract
To evaluate the influence of a different order of dentin and enamel layers on stratification appearance of different resin composites. 144 Dentin (D) and Enamel (E) composite samples (Clearfil Majesty ES-2 Premium, Brilliant EverGlow, Estelite Asteria), 1 mm thick, were divided into 12 configurations for each composite, with Enamel-Dentin-Dentin-Enamel (EDDE) assumed as target. The colour specification was conducted using a spectrophotometer, elaborating the results with the CIE L*a*b* colour coordinates and calculating the colour difference in terms of [Formula: see text] quantity. A value of this last major of 3.3 was considered not clinically acceptable. Moreover, data were analyzed using two-way analysis of variance and Tukey post hoc test (P < 0.05). For Clearfil Majesty ES-2 Premium and Brilliant EverGlow, six configurations showed [Formula: see text] > 3.3 compared to gold standard EDDE. [Formula: see text] was influenced especially by b* and L* coordinates (P < 0.05). EDED showed no visual difference (0 < [Formula: see text] < 1.1) for both composites. For Estelite Asteria, two configurations reported [Formula: see text] > 3.3 compared to EDDE. In particular, the L* coordinate influenced [Formula: see text] results (P < 0.05). EDDD was the best configuration (0 < [Formula: see text] < 1.1). Within the limits of a vitro study, Brilliant EG showed more dependence from order and thickness of stratification (resulting more similar to Clearfil Majesty ES-2 Premium); therefore, it could be indicated for more complex aesthetic restorations. Estelite Asteria seems to be able to balance small differences in thickness of dentin and enamel layers, and consequently, it is more indicated to different clinical situations.

Abstract
Only a few Herculaneum rolls exhibit writing on their reverse side. Since unrolled papyri are permanently glued to paperboard, so far, this fact was known to us only from 18th-century drawings. The application of shortwave-infrared (SWIR; 1000-2500 nm) hyperspectral imaging (HSI) to one of them (PHerc. 1691/1021) has revealed portions of Greek text hidden on the back more than 220 years after their first discovery, making it possible to recover this primary source for the ongoing new edition of this precious book. SWIR HSI has produced better contrast and legibility even on the extensive text preserved on the front compared to former imaging of Herculaneum papyri at 950 nm (improperly called multispectral imaging), with a substantial impact on the text reconstruction. These promising results confirm the importance of advanced techniques applied to ancient carbonized papyri and open the way to a better investigation of hundreds of other such papyri.

Abstract
Background Word comprehension across semantic categories is a key area of language development. Using online automated eye-tracking technology to reduce response demands during a word comprehension test may be advantageous in children with autism spectrum disorder (ASD). Objectives To measure online accuracy of word recognition across eleven semantic categories in preschool children with ASD and in typically developing (TD) children matched for gender and developmental age. Methods Using eye-tracker methodology we measured the relative number of fixations on a target image as compared to a foil of the same category shown simultaneously on screen. This online accuracy measure was considered a measure of word understanding. We tested the relationship between online accuracy and offline word recognition and the effects of clinical variables on online accuracy. Twenty-four children with ASD and 21 TD control children underwent the eye-tracking task. Results On average, children with ASD were significantly less accurate at fixating on the target image than the TD children. After multiple comparison correction, no significant differences were found across the eleven semantic categories of the experiment between preschool children with ASD and younger TD children matched for developmental age. The ASD group showed higher intragroup variability consistent with greater variation in vocabulary growth rates. Direct effects of non-verbal cognitive levels, vocabulary levels and gesture productions on online word recognition in both groups support a dimensional view of language abilities in ASD. Conclusions Online measures of word comprehension across different semantic categories show higher interindividual variability in children with ASD and may be useful for objectively monitor gains on targeted language interventions.

Abstract
Background: Kidney transplantation is considered the first-choice therapy in end-stage renal disease (ESRD) patients. Despite recent improvements in terms of outcomes and graft survival in recipients, postoperative complications still concern the health-care providers involved in the management of those patients. Particularly challenging are cardiovascular complications. Perioperative goal-directed fluid-therapy (PGDT) and hemodynamic optimization are widely used in high-risk surgical patients and are associated with a significant reduction in postoperative complication rates and length of stay (LOS). The aim of this work is to compare the effects of perioperative goal-directed therapy (PGDT) with conventional fluid therapy (CFT) and to determine whether there are any differences in major postoperative complications rates and delayed graft function (DGF) outcomes. Methods: Prospective study with historical controls. Two groups, a PGDT and a CFT group, were used: The stroke volume (SV) optimization protocol was applied for the PGDT group throughout the procedure. Conventional fluid therapy with fluids titration at a central venous pressure (CVP) of 8–12 mmHg and mean arterial pressure (MAP) >80 mmHg was applied to the control group. Postoperative data collection including vital signs, weight, urinary output, serum creatinine, blood urea nitrogen, serum potassium, and assessment of volemic status and the signs and symptoms of major postoperative complications occurred at 24 h, 72 h, 7 days, and 30 days after transplantation. Results: Among the 66 patients enrolled (33 for each group) similar physical characteristics were proved. Good functional recovery was evident in 92% of the CFT group, 98% of the PGDT group, and 94% of total patients. The statistical analysis showed a difference in postoperative complications as follows: Significant reduction of cardiovascular complications and DGF episodes (p < 0.05), and surgical complications (p < 0.01). There were no significant differences in pulmonary or other complications. Conclusions: PGDT and SV optimization effectively influenced the rate of major postoperative complications, reducing the overall morbidity and thus the mortality in patients receiving kidney transplantation.

Abstract
INTRODUCTION The Mayo technique is one of the most common techniques used to repair incisional, umbilical, and epigastric hernias. A high percentage of recurrences, together with the use of particular expensive types of meshes, are some of the most relevant problems in this surgical field. PATIENTS AND METHODS This study is a clinical prospective observational and involves all the patients who underwent procedures using a new modified Mayo technique from 2006 through 2013. The general criteria analyzed were age, sex, obesity, smoke abuse, diabetes, chronic diseases, type of hernia, operative time, morbidity and mortality. All the patients involved in this study were followed-up from 6 to 120 months. RESULTS The types of hernia were 5 epigastic hernia (20,8%), 8 umbilical hernia (33,3%), 11 midline incision hernia (45,9%). Ten patients (41,7%) presented non-complicated hernias; 8 patients (33,3%) presented strangulated hernias and 6 patients (25,0%) presented obstructed hernias. No intestinal resection was necessary in any of the patients. The mean operative time was 55 minutes (range 30-180). The mean hospital stay of the patients' after-post operative procedure was 4.5 days (range, 2 to 8 days). No major complications have been reported. Only one patient present a recurrence. CONCLUSION These preliminary results suggest that this modified Mayo technique could be useful in the armamentarium of surgeon to repair incisional, umbilical, and epigastric hernias. More studies are needed to validate the technique.

Abstract
We estimated the serum levels of SCC-Ag, CEA and TPA in 69 patients with head or neck neoplasia and 31 healthy patients using a radioimmunometric method (double antibody). SCC-Ag concentrations were significantly increased in 43.4% cancer patients with respect to the cut-off point value (1.7 ng/ml) of the control group, and the specificity was 96.7%. The data varied according to the evolutive phase of disease. Since the combined evaluation of SCC-Ag, TPA and CEA serum levels increased the sensitivity, that was 71.0%, we thought it opportune to use all these markers in the tumoral pahtology taken into consideration.

Abstract
Because of its physical and potassium-metabolic characteristics 201T1 is more suitable than 131Cs for radioisotopic studies of the cold thyroid nodule, with the further diagnostic possibility of quantitatively assessing intranodular behaviour for a specific differentiation among different kinds of neoformations. Using a gamma-camera on line with a computer data processing device, sequential scintiscans were recorded for the first 20-30 min after i. v. administration of 15-20 MCi\lkg of radiothallium; delayed sequences were taken at 40-60 min if intranodular uptake appeared. A quantitative appraisal was made of the differential 201Tl uptake-ratio between nodule and healthy thyroid tissue (density-index) and the multiparameter analysis of thyroid time/activity curves generated on the relative regions of interest (ROIs). This computerized study, in 120 out of 293 patients submitted to this radiothallium test, has shown a) diagnostic agreement between clinical-histological and radioisotopic findings in 76 out of 79 colloid-cystic or degenerative neoformations, in all 16 malignant and in 23 out of 25 hyperplastic benign nodules; b) significant statistical difference of the density-index in solid versus cystic but not between benign and malignant nodules; c) different 201T1 kinetics behaviour in different kinds of solid thyroid lesions with a satisfactory statistical difference of the radiothallium nodular dissapearance-index.

Abstract
PURPOSE Papillary thyroid carcinoma (PTC), the most common thyroid cancer histotype, has a good prognosis even when spread to the neck lymph node (LN). The prognostic role of LN metastases' location is still controversial. The aim of the present study was to evaluate the clinical relevance of the number and location of LN metastases at presentation in PTCs. METHODS This retrospective study included a consecutive series of 1653 PTC patients followed for a mean period of 5.9 years in a referral thyroid cancer clinic. All patients have undergone thyroidectomy with the dissection of at least six LNs. According to the LN status, patients were subdivided into 569 N0 (34.4%), 644 N1a (39.0%, central compartment) and 440 N1b (26.6%, latero-cervical compartment). RESULTS Age at diagnosis was significantly lower in N1b (39.8, IQR 30.7-51.6) and N1a (40.1, IQR 31.3-50.1) than in N0 (44.7, IQR 36.6-55.0 yrs). The male gender was more prevalent in N1b than in N1a and N0 (F/M = 1.9/1, 4.0/1 and 5.5/1, respectively). Persistent/recurrent disease at last control was significantly more frequent in N1b (29.8%) than in N1a (14.3%), and in N1a than in N0 (4.2%) (p < 0.01 for all). Also, distant metastases were significantly (p < 0.001) more frequent in N1b (14.1%) than in N1a (4.3%) and N0 (1.6%). LN metastases' number (>5) was a significant risk factor for persistent/recurrent disease only for N1a patients. CONCLUSIONS These data indicate that persistent/recurrent disease and distant metastases are significantly more frequent in patients with latero-cervical LN (N1b) metastases and that the LN location should be used for a better postsurgical risk stratification.

Abstract
OBJECTIVE Premonitory sensations or urges (PUs) are described as characteristic sensory phenomena preceding tics, which are often described as unpleasant. They occur in 90% of patients affected by Gilles de la Tourette Syndrome (GTS). They may be localized (around the area of tic) or generalized (covering a wide area of the body). The PUs can be measured by the Premonitory Urge for Tics Scale (PUTS). In this study we translated the PUTS scale into Italian and then assessed children and adolescents/young people (CYP) with GTS using the scale. METHODS GTS patients were assessed at the initial interview and after 7 years to evaluate the PUs, and the correlations of the PUTS scores with tic severity, severity of comorbid disorders (obsessive-compulsive disorder [OCD], attention-deficit/hyperactivity disorder [ADHD]), and a variety of coexisting psychopathologies. RESULTS A total of 95 patients were studied. We successfully translated the PUTS into Italian, and our results indicated that our translated version had good psychometric properties. Results demonstrated that the CYP had PUs at both interviews, but that older CYP were more consistent in reporting PUs than younger CYP (i.e., PUTS scores increased with age). We found no correlations between PUTS score and tic severity at either interview. We found a statistical significant correlation between PUTS score and obsessive-compulsive symptoms (OCS) at both interviews; Moreover both the PUTS and Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) scores increased significantly, whereas the Yale Global Tic Severity Rating Scale (YGTSS) score decreased significantly. We found no relationships between PUTS scores and anxiety, depression, ADHD, and externalizing/internalizing behavioral scores. CONCLUSIONS Our results suggest the the Italian translation of the PUTS has good psychometric properties. Although both younger (<10 years of age) and older CYP (≤ 10 years of age) reported PUs, the scores at the initial interview were statistically significantly lower than at follow-up. Moreover, in CYP >10 years of age, the PUs correlated with obsessions and compulsions (CY-BOCS scores).

Abstract
BACKGROUND To reduce the rate of recurrence of incisional hernia repair associated with open anatomic techniques, we present an experimental study, focusing on two different sutures, with the aim to apply clinically in a revised version of the Mayo technique. METHODS Thirteen biological tissue samples from adult pig central brawn and upper and lower fasciae were measured using two techniques defined as "unbroken suture thread" and "separated suture stitches" to test the breaking resistance of the two types of suture. RESULTS The t test results show that the two sets can be considered as different populations. The mean tensile stress max is greater (with reduced deviation) for the specimens of the set sutured with unbroken thread technique. Student's t-test performed on values obtained for each set of samples indicated that the unbroken thread suture technique corresponds to higher ultimate failure strength. CONCLUSION Considering these results, a modified Mayo technique with continuous closure could be suggested. Of course a valid clinical study is required to better clarify this experimental hypothesis.

Abstract
PURPOSE Psychiatric disorders could affect the patients' abilities to cope with diabetes. The objectives of this study were to assess the prevalence of depression and alexithymia among type 2 diabetic patients and investigate the possible correlations between these psychopathological phenomena and glycaemic control assessed through glycated hemoglobin (HbA1c). METHODS All the patients were evaluated through 20-item Toronto Alexithymia Scale (TAS-20), Hamilton rating scale for depression and Quality of Life Index. HbA1c values, diabetes duration, therapy and socio-demographic characteristics were recorded. RESULTS One hundred and twenty-eight patients (75 males and 53 female, mean age 64.7 ± 11.2 years) were enrolled. Alexithymic patients, compared to non-alexithymic ones, presented a significantly higher HbA1c (7.7 ± 1.5 vs. 7 ± 1.5, p = 0.016). No statistically significant difference was found when comparing the HbA1c of depressed versus non-depressed patients. Considering the raw values of HbA1c, the higher percentage was recorded among patients suffering from depression plus alexithymia (comorbidity group) followed by patients presenting alexithymia only, patients with neither depression nor alexithymia (control group) and, finally, those presenting depression only. The comorbidity group presented a significantly higher value of HbA1c (7.7 ± 1.2) than the control group (7 ± 1.6, p < 0.04) and the depressed patients (6.9 ± 1.3, p = 0.04). At the logistic regression, the HbA1c was found to be significantly associated only with alexithymia (TAS-20 total score) and insulin therapy. CONCLUSIONS Alexithymia more than depression influences glycaemic control. When evaluating a diabetic patient, a rapid screening for psychopathological alterations would guarantee a more accurate management. The treatment of any associated psychiatric disorders would improve the patients' quality of life.

Abstract
BACKGROUND AND AIMS Due to the worldwide increasing prevalence of diabetes (DM), patients with both diabetes and Graves' disease (GD) have become more frequent. Sporadic reports indicate that Graves' orbitopathy (GO), a GD complication that affects orbital soft tissues, can be severe in DM patients. The relationship between these diseases is not well understood. This study aims at evaluating the association of GD and GO with autoimmune and non-autoimmune diabetes (DM) and to assess diabetic features that influence GD and GO prevalence and severity. METHODS AND RESULTS This retrospective study evaluated GD, GO and DM association in 1211 consecutive GD patients (447 with GO and 77 with DM). A case-control study was carried out to evaluate DM relationship with GO severity by comparing at 1:2 ratio GO patients with or without DM. A strong association was found between GD and T1DM (p = 0.01) but not T2DM. Instead, the presence of GO was strongly associated with T2DM (p = 0.01). Moreover, GO was more frequently severe in GD patients with T2DM (11/30 or 36.6%) than in those without T2DM (1/60 or 1.7%, p = 0.05). T2DM was the strongest risk factor for severe GO (OR = 34.1 vs. 4.4 p < 0.049 in cigarette smokers). DM duration, obesity and vascular complications, but not metabolic control were significant determinants of GO severity. CONCLUSIONS GD is associated with T1DM but not with T2DM, probably because of the common autoimmune background. GO, in contrast, is more frequent and severe in T2DM, significantly associated with obesity, diabetes duration and diabetic vasculopathy but not metabolic control.

Abstract
Background We evaluated treatment modalities and survival in patients with hepatocellular carcinoma (HCC), by pre-treatment and 3-month post-treatment serum alpha-fetoprotein (AFP) levels and pre-treatment tumor diameters. Methods We retrospectively reviewed 57 patients treated for HCC in our department from January 2002 to December 2012, including their sex, type of hepatitis, Child class, pre-treatment tumor size, pre-treatment levels of albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyltransferase (GGT), red blood cells, hemoglobin, and total bilirubin, pre- and 3-month post-treatment serum AFP, and treatment modality (transarterial chemoembolization, resection or radiofrequency ablation). Survival was analyzed at 1, 3, and 5 years after treatment. Results The 57 patients included 44 men and 13 women, of whom 44 had hepatitis C virus (HCV) infection, 3 had hepatitis B virus (HBV) infection, 3 had both HBV and HCV infection, 1 had both HBV and hepatitis D virus infection, and 3 had alcohol-related liver cirrhosis. Both pre- and post-treatment serum AFP levels significantly correlated with recurrent tumor size (P < 0.05 for both). Pre-treatment tumor size did not correlate with recurrent tumor size. Patients who underwent hepatic resection survived significantly longer than those who underwent transarterial chemoembolization or radiofrequency ablation (P < 0.05). Conclusions Serum AFP level is useful in diagnosing tumor recurrence and predicting prognosis in HCC patients treated by hepatic resection, transarterial chemoembolization, and radiofrequency ablation. Hepatic resection remains the treatment of choice for HCC in suitable patients.

Abstract
Background It is well established in studies across several countries that tobacco smoking is more prevalent among schizophrenic patients than the general population. Electronic cigarettes are becoming increasingly popular with smokers worldwide. To date there are no large randomized trials of electronic cigarettes in schizophrenic smokers. A well-designed trial is needed to compare efficacy and safety of these products in this special population. Methods/Design Intervention: We have designed a randomized controlled trial investigating the efficacy and safety of electronic cigarette. The trial will take the form of a prospective 12-month randomized clinical study to evaluate smoking reduction, smoking abstinence and adverse events in schizophrenic smokers not intending to quit. We will also monitor quality of life, neurocognitive functioning and measure participants’ perception and satisfaction of the product. Outcome measures: A ≥50% reduction in the number of cigarettes/day from baseline, will be calculated at each study visit (“reducers”). Abstinence from smoking will be calculated at each study visit (“quitters”). Smokers who leave the study protocol before its completion and will carry out the Early Termination Visit or who will not satisfy the criteria of “reducers” and “quitters” will be defined “non responders”. Statistical analysis: The differences of continuous variables between the three groups will be evaluated with the Kruskal-Wallis Test, followed by the Dunn multiple comparison test. The differences between the three groups for normally distributed data will be evaluated with ANOVA test one way, followed by the Newman-Keuls multiple comparison test. The normality of the distribution will be evaluated with the Kolmogorov-Smirnov test. Any correlations between the variables under evaluation will be assessed by Spearman r correlation. To compare qualitative data will be used the Chi-square test. Discussion The main strengths of the SCARIS study are the following: it’s the first large RCT on schizophrenic patient, involving in and outpatient, evaluating the effect of a three-arm study design, and a long term of follow-up (52-weeks). The goal is to propose an effective intervention to reduce the risk of tobacco smoking, as a complementary tool to treat tobacco addiction in schizophrenia.

Abstract
BACKGROUND/AIMS The Barcelona Clinic Liver Cancer (BCLC) classification has been recently validated as the best system for treatment guidance for hepatocellular carcinoma (HCC). The aim of this retrospective study is to evaluate the usefulness of BCLC in the treatment of HCC comparing our treatment decision and the BCLC algorithm indications. METHODOLOGY In 102 patients affected by HCC observed from 1991 to 2002 a retrospective analysis was performed. The choice of treatment was compared with the treatment schedule proposed by BCLC. Whereas the second group of 62 patients observed from 2008 to 2010 was analysed both retrospectively in comparison with the BCLC classification. RESULTS We found a disagreement in between our decision making and the choices suggested by BCLC. We only found a statistical significance for age and performance status test. In surgical patients the median age and the PST class were lower with a statistically significant p value (0.04 and 0.03, respectively). CONCLUSIONS The BCLC system would not have changed our decision either in the past, or in present days, especially in surgical indications. Even if the decision making is affected by BCLC, actually that process still needs the support of the experience of each clinical centre involved.

Abstract
OBJECTIVES Across Europe, more than one third of patients are diagnosed with HIV infection late. Late presentation for care has been associated with higher risk of clinical progression and mortality. In the present study, we evaluated the prevalence, epidemiological characteristics and survival probability of patients with late and very late presentation, newly diagnosed with HIV infection in Catania, Italy, from 1985 to 2010. PATIENTS AND METHODS According to the European Consensus definition, Late Presenters (LP) were defined as subjects presenting for care with a CD4+ T-cell count below 350 cells/µl or with an AIDS-defining event, regardless of CD4+ T-cell count; patients with advanced HIV disease (Very Late Presenters) (VLP) were those presenting with a CD4+ T-cell count below 200 cells/µl or with an AIDS-defining event, regardless of CD4+ T-cell count. RESULTS 620 patients were included in the study. 345 (55.6%) subjects were LP, 35% of them were asymptomatic; 246 (39.7%) were VLP. In univariate analysis, late presentation was related to age (p < 0.001), to heterosexual exposure to HIV infection (70% of heterosexual subjects were LP) (p < 0.005) and to being diagnosed during the calendar period from 1991 to 2000 (p < 0.001). Very late presentation was related to age (p < 0.001), male sex (p < 0.01), heterosexual risk (p < 0.001) and to being diagnosed during the calendar period from 1991 to 2000 (p < 0.001). In multivariate analysis, age (p < 0.0001), being older than 50 years old (p = 0.02), years of diagnosis 1991-1995 (p < 0.005) and 1996-2000 (p < 0.05) in the subgroup of late presenters and age (p < 0.0001), being older than 50 years old (p < 0.005), male sex (p < 0.0001), years of diagnosis 1991-1995 (p < 0.05) and 1996-2000 (p < 0.005) in the subgroup of very late presenters maintained statistical significance. The survival probability within LP and VLP group was statistically lower than no LP/VLP (log rank test p < 0.0005 and p < 0.0001, respectively). For both LP (p < 0.002) and VLP (p < 0.0001), survival probability was significantly lower in the pre-HAART era, in comparison with the period of mono/dual therapy and the HAART era. CONCLUSIONS More than fifty percent of patients in our setting were diagnosed late with HIV infection and, consequently, treated late. Late and very late presentation were associated with lower survival probability. The implementation of strategies focused on targeted prevention efforts and HIV testing programs appears fundamental to diagnose and treat HIV infection as early as possible.

Abstract
AIM Vitamin D deficiency is very common among HIV-infected subjects. We cross-sectionally evaluated the prevalence and risk factors for hypovitaminosis D in 91 HIV-infected Italian patients. PATIENTS AND METHODS We studied in a cohort of 91 HIV-infected Italian patients the metabolism of Vitamin D by evaluating the in vitro expression of CYP27B1, CYP24A1 and vitamin D receptor (VDR) by monocytes and macrophages stimulated with the viral envelope protein gp120 or lipopolysaccharide (LPS). RESULTS The prevalence of vitamin D deficiency (25OHD < 10 ng/ml) and vitamin D insufficiency (25OHD 10-30 ng/ml) was 31% and 57%, respectively. In univariate analysis, female sex (p = 0.01), increasing age (p = 0.05), higher highly sensitive-C reactive protein (p = 0.025), higher parathyroid hormone (PTH) (p = 0.043) and lower BMI (p = 0.04) were associated with vitamin D deficiency. In multivariate analysis, the association was still significant only for PTH (p = 0.03) and female sex (p = 0.03). Monocyte stimulation with LPS (100 ng/ml) or gp120 (1 µg/ml) significantly upregulated CYP27B1 mRNA expression. Moreover, gp120 significantly increased VDR mRNA levels. On the contrary, neither LPS nor gp120 modified CYP24A1 levels. Macrophage stimulation with LPS (100 ng/ml) significantly upregulated CYP27B1 and CYP24A1 mRNA expression. When monocytes were cultured in the presence of 25OHD (40 ng/ml) and stimulated with LPS we detected significantly lower levels of 25OHD in the supernatant. CONCLUSIONS Vitamin D deficiency was very common in our cohort of HIV-infected patients. Chronic inflammation, including residual viral replication, may contribute to hypovitaminosis D, by modulating vitamin D metabolism and catabolism. Systematic screening may help identifying subjects requiring supplementation.

Abstract
PURPOSE The purpose of this systematic review is to evaluate and compare the risk of dissemination metastasis (wound, port-side metastases and peritoneal seeding) after laparoscopic colorectal surgery and conventional open surgery for colorectal cancer. MATERIALS AND METHODS The Authors searched relevant randomized controlled trials between January 1998 and July 2012. RESULTS Wound, port-site metastases and peritoneal seeding were rare and no significant differences occurred between the two groups. The port-site and extraction site recurrence were likely to be the results of suboptimal surgical techniques and occurred in the early phase of the learning curve. The authors also found no significant differences in overall, local and distant recurrences. No significant differences between laparoscopic and open surgery were found in cancer-related mortality during the follow up period of the study (7 RCTs, 3525 patients, 12.8% vs. 14.00%; OR (fixed) 0.83, 95% CI 0.68-1.02), with no significant heterogeneity (p = 0.35). CONCLUSIONS The literature supports the implementation of laparoscopic surgery into daily practice. Laparoscopic surgery can be used for safe and radical resection of cancer in the right, left, sigmoid colon and rectum. However further studies should address whether laparoscopic surgery is superior to open surgery in this setting.

Abstract
PURPOSE The purpose of this study was to evaluate Interferon (IFN)-γ and Interleukin(IL)-17 profiles in patients with different clinical presentations of pulmonary tuberculosis (TB) and to compare them with those of tuberculin-negative and tuberculin-reactive healthy controls METHODS Peripheral blood mononuclear cells (PBMCss), isolated from patients (n=52) and controls (n=30), were stimulated ex vivo with purified protein derivative (PPD) and IFN-γ and IL-17 levels in the supernatant were measured. RESULTS At baseline, PBMCss from patients with TB released a significantly lower amount of IL-17 (p=0.043) than PBMCss from healthy controls, whereas IFN-γ levels were similar in the two groups. After PPD stimulation, a significant rise in IL-17 levels was found only among healthy controls (p=0.02). This rise in IL-17 levels was similar between tuberculin-reactive and tuberculin-negative subjects. After PPD stimulation, patients with infiltrative TB secreted higher levels of IL-17 and IFN-γ than those affected with chronic, miliary and cavitary TB (p < 0.01). IFN-γ production from patients with infiltrative TB was even higher than for healthy controls (p < 0.01). PBMCss from tuberculin-reactive patients released higher levels of IFN-γ than tuberculin-negative subjects after PPD stimulation (p < 0.01). CONCLUSION Ex vivo PPD stimulation of PBMCs from patients with pulmonary TB does not significantly stimulate IL-17 release; however, higher IL-17 and IFN-γ levels are found in patients with infiltrative disease, in comparison with those affected with miliary, cavitary and chronic TB.

Abstract
INTRODUCTION Anxiety disorders are frequent in HIV-infected individuals, can pre-exist or occur during HIV infection. We evaluated with a self-reported questionnaire whether anxiety is related to HIV clinical status and therapeutic success in a cohort of HIV-positive subjects in Sicily. PATIENTS AND METHODS We enrolled 251 patients on combination antiretroviral therapy (cART) for at least six months; Self Rating Anxiety State SAS 054 was used to diagnose anxiety and a Z score ≥ 45 points was considered diagnostic. RESULTS 47% of patients were diagnosed with anxiety. Patients showing symptoms related to anxiety had experienced a high number of therapeutic switches (fourth line or more). CONCLUSIONS These data confirm a high prevalence of anxiety symptoms among subjects with HIV infection in Eastern Sicily. Physicians should be aware of the extent of the problem and should be able to adequately manage anxiety in the setting of HIV infection.

Abstract
BACKGROUND IL-33 is a novel member of the IL-1 family, which has been shown to play an important role in T helper 2 (Th2)-associated immune responses. Recent studies have suggested a possible role for IL-33 in the pathogenesis of liver damage during acute and chronic hepatitis; furthermore, IL-33 may be involved in the development and progression of liver fibrosis. OBJECTIVES To evaluate serum IL-33 levels in a group of patients with chronic hepatitis C (CHC) genotype 1b at enrolment and after a course of pegylated (PEG)-IFN plus ribavirin. PATIENTS AND METHODS 60 patients with chronic hepatitis C (CHC) and 65 healthy controls were examined and compared for serum IL-33 levels by ELISA. All CHC patients were submitted to liver biopsy either before starting antiviral treatment or during post-treatment follow up. We evaluated whether post-treatment IL-33 concentration was associated with histologic outcome as well as with virologic response to therapy. RESULTS Serum IL-33 levels were significantly higher among CHC patients in comparison with healthy controls. IL-33 concentration was lower among patients with a METAVIR fibrosis score F1-F2, compared with those having a more advanced liver disease (METAVIR stage F3-F4). In addition, sustained virologic response (SVR) was associated with a significant drop in IL-33 levels, whereas no changes were found among relapsers and nonresponders. Analogously, patients experiencing liver histologic improvement after antiviral therapy had lower post-treatment IL-33 levels in comparison with baseline values. Contrarily, no variations were detected among subjects with worsened or stable histologic features. CONCLUSIONS IL-33 may represent a new and easy-to-detect biomarker for the diagnosis of liver damage in CHC patients, as it appears to be modulated in parallel with biochemical and histologic parameters, such as ALT levels and liver fibrosis. Furthermore, considering that serum IL-33 concentration was significantly reduced following a successful course of antiviral treatment, this cytokine may also represent a sensitive indicator of SVR.

Abstract
AIM To assess resistance to cyclic fatigue of reciprocating nickel-titanium ( NiTi ) files (Reciproc and WaveOne) after immersion in NaOCl solution over several time periods. METHODOLOGY A total of 90 new Reciproc R25 and WaveOne Primary were tested. The 45 files of the same brand were randomly assigned to three groups (n = 15) and submitted to the following immersion protocol in 5% NaOCl at 37 °C for 16 mm: no immersion (control), 1 or 5 min dynamically. The dynamic immersion and the following cyclic fatigue tests were performed using the appropriate preset reciprocation modes ('RECIPROC ALL' or 'WAVEONE ALL') in a specially designed endodontic motor. Resistance to cyclic fatigue was determined by recording time to fracture (TtF) in a stainless steel artificial canal with a 60° angle of curvature and 5 mm radius of curvature. The artificial canal was manufactured reproducing the instrument's size and taper. Data were analysed by 2-way analyses of variance. RESULTS Resistance to cyclic fatigue of the same NiTi file was not significantly affected by immersion in NaOCl . Reciproc R25 was associated with a higher cyclic fatigue resistance in all groups compared to WaveOne Primary (P < 0.0001). CONCLUSIONS Reciprocating dynamic immersion in NaOCl for 1 or 5 min did not reduce the cyclic fatigue resistance of NiTi files significantly. However, the type of reciprocating instrument influenced cyclic fatigue resistance with Reciproc R25 being more resistant than WaveOne Primary.

Abstract
BACKGROUND Italian Legislative Decree No. 81/2008 foresees the involvement of a "specialised physician" in activities for the promotion of health at the workplace. OBJECTIVES These activities are aimed at modifying erroneous lifestyles (such as smoking, drinking, bad diet, etc.) which are responsible for serious illnesses and also for repercussions on the assessment of fitness for a specific task. Obesity, as we know, represents the major risk factor in the onset of metabolic, neoplastic, cardiovascular and respiratory diseases and also in the increased incidence of accidents at the workplace and sick absence. METHODS A specific questionnaire was administered to 700 health care workers of a Hospital in Catania to estimate the incidence of factors which favour the onset of these diseases: factors such as familiarity, endocrinal dysfunction problems (diabetes mellitus, hypothyroidism), shift work and little physical exercise. RESULTS AND CONCLUSION Statistical processing of the data confirmed, partially, that little physical exercise, hypothyroidism, diabetes mellitus, familiarity in the > 36 age group were the major risk factors in the onset of obesity, as reported in the literature. However, contrary to the literature reports, shift work did not seem to be a risk factor in the sample under study. A programme of rehabilitation, on a voluntary basis, will be offered to those workers who are overweight/obese. This programme will involve professionals such as nutritionists, endocrinologists and psychologists, and it will aim at improving workers' health conditions as well as their work performance.

Abstract
BACKGROUND AND AIMS Metabolic syndrome (MS) has been mainly related to insulin resistance, but the role of changes in insulin secretion has not been thoroughly investigated. METHODS AND RESULTS Using an oral glucose tolerance test (OGTT) we studied beta-cell function and insulin sensitivity in subjects with normal fasting glucose with and without MS, and their relationship to fatty liver which was evaluated by abdominal-ultrasonography. In MS early phase insulin secretion, as measured by insulinogenic index (IG(30)), was increased (p<0.05) independently from insulin sensitivity. Furthermore IG(30) was progressively higher as the number of factors needed for the diagnosis of MS increased (p<0.01). Insulin and C-peptide AUC were also increased (p<0.01 and p<0.05, respectively) but, in contrast to IG(30), these differences disappeared when ISI was used as a covariate. After OGTT, 51% of the subjects with MS had altered post-load glucose tolerance compared to 24.9% without MS (p<0.01). In both groups, the altered glucose tolerance was associated with a similar IG(30) reduction. In normo-tolerant subjects with MS the IG(30) was higher (+54.1%, p<0.01), and this elevation occurred irrespective of ISI; however, the beta-cell compensatory capacity for insulin resistance (disposition index) was impaired (p<0.001). Fatty liver was more frequent (p<0.001) and more severe (p<0.01) in MS, and it was significantly related to total AUC-insulin (p<0.001), independently from ISI. CONCLUSION These findings indicate that the prevalence of altered tolerance is more frequent in subjects with normal fasting glucose and MS. The hyperinsulinemia might not only be an adaptive response to insulin resistance, but a primary defect of beta-cell function contributing to glucose intolerance.

Abstract
OBJECTIVE To evaluate the efficacy of probiotics in the prevention of gastrointestinal colonization by Candida species, of late-onset sepsis and neurological outcome in preterm newborns. STUDY DESIGN A prospective study was conducted in 249 preterms who were subdivided into three groups: one group (n=83) was supplemented with Lactobacillus (L.) reuteri, one group with L. rhamnosus (n=83) and the other with no supplementation (n=83). The fungal colonization in the gastrointestinal tract, the late onset of sepsis and clinical parameters were recorded. A neurological structured assessment was further performed at 1 year of age. RESULT Candida stool colonization was significantly higher (P<0.01) in the control group than in the groups treated with probiotics. The L. reuteri group presented a significantly higher reduction in gastrointestinal symptoms than did the L. rhamnosus and control groups. Infants treated with probiotics showed a statistically significant lower incidence of abnormal neurological outcome than did the control group. CONCLUSION The use of both probiotics seems to be effective in the prevention of gastrointestinal colonization by Candida, in the protection from late-onset sepis and in reducing abnormal neurological outcomes in preterms.

Abstract
AIM In the different psychiatric disorders the aggression often leads to uncontrolled events, taking aspects of impulsiveness and irrationality. Our research proposes the assessment of socio-demographic and clinical characteristics of patients with a psychiatric disorder, who presented an aggressive event. METHODS The observational study was conducted on a sample of 50 patients (34 men and 16 women), hospitalized following the manifestation of an aggressive event. For each patient was provided an assessment of socio-demographic and clinical variables and a psychometric investigation through: the OAS, for the analysis of aggressive episodes; the BDHI, for the hostile behavior and attitudes; the BIS-11, for the impulsiveness and the BPRS for the psychopathological aspects. RESULTS Among the socio-demographic features investigated, the highest correlation with aggressive behavior was related to the concomitant substance abuse, type of admission to psychiatric hospital and the male gender. The OAS has shown a greater propensity to directed-aggression in males with schizophrenia, and self-directed in females with major depression. The BPRS has shown a positive correlation between hetero-directed aggressive behavior and positive symptomatology, and between the self-directed and depression, risk of suicide, feelings of guilt and somatic concerns. The BDHI has indicated greater suspicion in women's group. DISCUSSION The hypothesis that aggression is otherwise related to specific socio-demographic and clinical characteristics was confirmed by our study. The data suggest that early identification and assessment of potential risk factors involved in the genesis of aggressive episodes would allow the clinician to implement a better strategy for prevention and intervention.

Abstract
Surrogate markers of liver fibrosis are needed as an alternative to liver biopsy, which is invasive and life-threatening. Peripheral blood fibrocytes (PBF) are considered to be involved in systemic fibrogenic processes. We measured the level of PBF in patients with chronic hepatitis C by enrolling 70 patients affected with chronic hepatitis C, 20 patients with HCV-positive decompensated cirrhosis and 30 healthy volunteers. All patients underwent liver biopsy and Fibroscan for fibrosis assessment. Patients with chronic hepatitis C had significantly higher levels of PBF in comparison with healthy individuals and decompensated cirrhotics. Patients in the F0-F1 stage had a percentage of PBF of 23.3+/-4%, significantly lower (p<0.001) than in F2 and F3 stages. Patients in the F4 stage had a PBF rate of 50.6+/-2% (p<0.001 versus the F0, F1 and F2 stages). The percentage of PBF correlated positively with the Metavir score and the liver stiffness as measured by Fibroscan. PBF are increased in patients with HCV infection and correlate with the histological stage of liver fibrosis.

Abstract
Bronchial hyperresponsiveness to 5-adenosine mono-phosphate (AMP) is a marker of airway inflammation. Inhaled corticosteroids and antileukotrienes are used as anti-inflammatory drugs for the treatment of asthma. To find out if these two drugs exert their protection in an additive fashion, we compared the effects of acute treatment with inhaled beclomethasone (BDP) and montelukast (ML), alone or in combination, on methacholine and AMP induced bronchoconstriction. 15 asthmatic patients undertook methacholine and AMP challenges at baseline and after receiving ML or BDP, alone or in combination, in a randomized, double-blind, double-dummy placebo-controlled, crossover design. BDP pretreatment significantly increased the AMP PC(20) value (68.34+/-15.9mg/mL) as compared to placebo (22.87+/-5.7mg/mL). Combined treatment, BDP plus ML, afforded a further significant increase of AMP PC(20) (154.57+/-55.0mg/mL) as compared to each single treatment. The significant protection exerted by combined treatment as compared to each single active treatment was also demonstrated by the change of AMP PC(20) doubling dose as compared to placebo and each single active treatment. Our findings suggest that these two agents exert their acute additive protection against AMP induced bronchoconstriction acting on distinct inflammatory pathways and their combined use might provide greater protection against inflammatory response elicited by AMP than either drug alone.

Abstract
BACKGROUND Vascular damage of frontal-subcortical circuits involved in mood regulation and cognition might be the main contributor to the pathogenesis of late-life depression, and it is linked to poor response to treatment. OBJECTIVE To investigate the relationship between executive dysfunction and outcome of depressive symptoms among elderly patients with subcortical ischemic vascular disease. METHODS Ninety-two elderly patients with white matter lesions (WMLs) or lacunar infarcts (LAs) on brain MRI and depressive symptomatology were consecutively recruited. Depression was rated with the Hamilton Depression Rating Scale (HDRS). Evaluation of executive functions by means of the Stroop color-word test was performed at entry of the study, and WMLs were categorized into mild, moderate or severe. Mood was reevaluated by means of HDRS after the 12th week of pharmacological treatment. RESULTS Psychomotor retardation, difficulties at work, apathy, and lack of insight were the predominant symptoms. Fifty-six patients (62.8%) had a neuroradiological picture of WMLs, while the remaining 33 (37.1%) had LAs. Executive dysfunctions significantly and independently predict poor outcome of depressive symptoms. Patients with the severest WMLs showed not only a greater executive dysfunction, but also a minor response to antidepressant treatment. CONCLUSION This study supports the vascular depression hypothesis. WMLs are of crucial clinical relevance as they are linked with cognitive symptoms and poor antidepressant outcome.

Abstract
BACKGROUND Near term infants are a main part of preterms. They are at higher risk for mortality and morbidity than term infants and could show a quite different development of tone and reflexes from them. The aim of the present study was to describe longitudinally, in a large sample of healthy near term infants, the development of the forward parachute reaction (FPR) and its correlation with the age of acquisition of independent walking. METHODS The assessment of FPR (as absent, incomplete or complete) was performed at 3, 6, 9, 12 months of corrected age in 484 infants, with a gestational age between 35.0 and 36.9 weeks. The age of acquisition of independent walking was monitored until its appearance. A correlation analysis was done between the age of walking and the acquisition of a complete or incomplete FPR, using the Spearman Rank correlation. The Mann-Withney U test was used to identify significant gestational age differences for the age of FPR appearance. RESULTS Most of infants had a two-step development pattern. In fact, they showed at first an incomplete and then a complete FPR, which was observed more frequently at 9 months. An incomplete FPR only, without a successive maturation to a complete FPR, was present in the 21% of the whole sample. Infants with a complete FPR walked at a median age of 13 months, whereas those with an incomplete FPR only walked at a median age of 14 months. CONCLUSION We identified two groups within our sample of near term infants. The first group showed a progressive maturation of FPR, whereas the second one was characterised by the inability to get a complete pattern, within the one year observation's period. Furthermore, we observed a trend toward a delayed acquisition of independent walking in the latter group of infants.

Abstract
There is much concern about the increasing presence in the environment of synthetic chemicals that are able to disrupt the endocrine system. Among these compounds, 4-nonylphenol (4-NP) is one of the most studied xenoestrogens, due to its widespread accumulation in water sediment and consequent presence in fatty acid of aquatic organisms. Here, we have used a zebrafish microarray representing 16,399 genes to study the effects of 4-NP and estradiol-17beta (E2) in adult male zebrafish in order to elucidate the mechanism of action of 4-NP compared with that of E2. The microarray results showed that both 4-NP and E2 induced a strong expression of vitellogenin (VTG), the sex related precursor of the yolk proteins in oviparous vertebrates. Both treatments induced elevated protein turnover upregulating genes involved in proteolysis and those that are constituents of the ribosome. Many genes regulated by 4-NP and E2 are involved in energy metabolism, oxidative stress defense mechanisms, xenobiotic metabolism, and lipid metabolism. A different pattern of expression in the two treatments was found for genes involved in oxidative stress, since E2 seems to induce the mechanism of detoxification, while 4-NP seems to inhibit this protective mechanism of the cell. Overall, these findings demonstrate that the microarray approach can contribute significantly to the understanding of expression patterns induced by E2 and 4-NP in male zebrafish. The results also demonstrate that 4-NP is able to act through an alternative pattern to that of estradiol-17beta, modulating the expression of the same genes in a different manner.

Abstract
IL-8 serum levels were measured in a group of 44 patients affected with Chronic Active Hepatitis (CAH) HCV+ at the beginning and end of peg-interferon plus ribavirin combined therapy. IL-8 levels were compared with those measured in a group of healthy controls. The patients were treated for 12 months, and then followed up for 6 months after the end of the therapy. IL-8 serum levels were detected by ELISA at the beginning and end of the therapy, and then at the end of the follow-up. IL-8 serum levels were significantly more elevated (p<0.01) in CAH HCV+ patients than in the healthy controls. Furthermore, IL-8 serum levels in those patients who subsequently showed a sustained virological response to the therapy, declined on treatment and maintained lower levels than in those who did not respond to therapy. Serum IL-8 can be considered and proposed as a non-invasive and predictive marker of response to combined PEG IFN alpha2b + Ribavirin in CAH HCV +.

Abstract
BACKGROUND The Hammersmith Infant Neurological Examination (HINE) is a simple and scorable method for assessing infants between 2 and 24 months of age. AIMS The purpose of this retrospective study was firstly, to evaluate the neuromotor development of infants with cerebral palsy (CP) by the HINE, during the first year of age; secondly, to correlate the scoring of this neurological tool with levels of the Gross Motor Function Classification System (GMFCS). METHODS A cohort of 70 infants with a diagnosis of CP at 2 years of age was evaluated by the HINE at 3, 6, 9 and 12 months of corrected age and by GMFCS at 2 years of age. RESULTS The main results indicate that at 3-6 months, infants with quadriplegia (IV and V levels of GMFCS) and those with severe diplegia (III level) scored below 40, whereas those with mild or moderate diplegia (I-II level) and hemiplegia (I-II level) mainly scored between 40-60. Interestingly, the 26% of infants with hemiplegia scored > or =67 at 12 months. We observed a strong (r=-0.82) and significant (p<0.0001) negative correlation between the scores of the neurological examination and the levels of GMFCS. CONCLUSIONS Our results point out that the HINE can give additional information about neuromotor development of infants with CP from 3-6 months of age, strictly related to the gross motor functional abilities at 2 years of age.

Abstract
Proopiomelanocortin (POMC) is an important gene implicated in different functions, such as the stress response of the hypothalamus-pituitary-adrenal axis. The aim of the present study was to determine whether farming conditions, such as stocking density, can be considered a powerful stressor influencing in turn the growth rate in juvenile fish. Thus, POMC cDNA expression was investigated during adaptation to farming conditions in sole (Solea solea), as a model for studying the effects of rearing densities on stress response; different stocking densities (50, 100, and 250 animals/m(2)) were applied and, after 7 and 21 days, the fishes were examined for body weight and plasma cortisol levels as indicators of stress. In addition, proopiomelanocortin was cloned and sequenced from the brain of sole, allowing semi-quantitative RT-PCR to be performed to evaluate POMC mRNA expression in brain tissue. There was a significant increase in cortisol levels in fish reared at high stocking densities of 250/m(2) compared to fish reared at control densities of 100 and 50/m(2), in both experimental times, i.e., 7 and 21 days. The high stocking densities were also found to decrease the specific growth rate of fish. Moreover, it was demonstrated that the highest stocking density induced a significant decrease in sole POMC mRNA expression. It is concluded that POMC and cortisol are both involved in the stress response due to high rearing densities, during which cortisol may serve as a negative regulator of POMC.

Abstract
The aim of this study was to follow the evolution of neurological findings in a cohort of near-term infants born between 35 and 37 weeks. A total of 448 infants born between 35 and 36.9 weeks gestational age with normal cranial ultrasonograms or only minor abnormalities, were studied using the Hammersmith Infant Neurological Examination, at 6, 9 and 12 months (corrected for prematurity). Our results showed that while some items such as cranial nerve and movements showed minimal changes over time, other items mainly related to "tone", "posture" and "reflexes" showed progressive maturation. There was no significant difference between the infants born at 35 and 36 weeks gestation. When compared to term infants assessed at the same age intervals, our cohort showed a wider variability of scores. Mean and 10 (th) percentile for global scores were lower than those reported for term infants suggesting that when assessing infants born at 35 and 36 weeks the optimality scores used for infants born full-term should not be used as normative data. Our results, providing longitudinal data in near-term infants without brain lesions, can be used as a reference in both clinical and research setting to monitor early neurological signs in those children.
